Building the simplest way to contribute to science.
A unified, public catalogue of clinical trials, registries, databases, and programs where people contribute their own data or samples—including paid, donation, and volunteer options.
The Challenge
Many programs already exist—but without shared infrastructure, it's hard for people to navigate the full landscape. We believe everyone benefits when information is unified and accessible.
Scattered Landscape
Registries, donation portals, directories, databases, and services all exist independently—spanning data types from genomes and clinical trials to wearables and microbiome donations—making it hard for anyone to see the full picture.
Geographic Complexity
Understanding where an opportunity is available—whether globally or in a specific country—often takes effort. A simple, normalized view would help everyone.
Missing Context
Details like the nature of an organization—academic, non-profit, government, or commercial—its location, and compensation structure are valuable but not always easy to find or compare.
No Shared Catalogue
There is no standardized, open catalogue that describes all these programs in one place—with structured, machine-readable information that anyone can access, reuse, and build upon.
Our Solution: A Unified, Open Catalogue
By standardizing descriptions—normalizing country, data types, organization, and compensation—we make discovering and comparing opportunities frictionless.
A clear, structured catalogue helps people find the right programs, helps researchers gain visibility, and makes science participatory for everyone.
An Open Dataset for Everyone
We believe science data should be a shared foundation for discovery. To support seamless collaboration across all communities and sectors, our entire catalogue is an Open Dataset dedicated to the Public Domain (CC0 1.0 Universal). Additionally, our website content is available under CC BY-SA 4.0, and our platform code is open-source under AGPL-3.0.
- Downloadable: Access the full dataset in multiple structured formats (JSON, CSV, Markdown) directly from our Data Portal.
- No Restrictions: Researchers, platforms, and AI systems can use, modify, and distribute the data without asking permission.
- Community Verified: Data is continuously vetted and expanded through public GitHub contributions.
- Enriching Open Knowledge: We are actively integrating our public domain dataset into Wikidata. By serving as a verifiable reference source (currently cited on 31 unique items), we help ensure the global knowledge graph—and the AI systems trained on it—has accurate, structured information on scientific participation.
Who This Empowers
An open catalogue benefits everyone. We bring together the information that helps people find the right programs and helps programs find the right people.
Citizens & Communities
Browse opportunities by location, data type, and interest—from volunteer participation to paid compensation. The simplest way to find your place in science.
Researchers & Clinicians
Gain visibility for your study. A structured, open catalogue makes it easier for potential participants to discover your program.
Platforms & Innovators
Increase discoverability by being listed alongside other programs in a standardized, open, and machine-readable catalogue.
Academic & Public Institutions
Gain visibility for your programs in a comprehensive catalogue accessible across geographic boundaries.
Investors & Funders
The only structured, open index of the citizen science participation market. Filter, compare, and export data to inform investment and funding decisions.
Explore the dataPolicy Makers & Analysts
Analyze the landscape across jurisdictions, organization types, and compensation models. Our open data supports evidence-based science policy.
Explore the dataOur Core Principles
Science belongs to everyone. We are built on foundations of transparency, access, and community.
Radically Open
Dataset (Public Domain), content (CC BY-SA 4.0), and code (AGPL-3.0) are openly licensed.
Community-Driven
A collaborative ecosystem welcoming contributions from a global base.
Accessible
Built for everyone. Maintained with a perfect Lighthouse Accessibility score.
AI-Ready
Public domain data, open-source code, and an llms.txt file make the catalogue fully accessible to AI systems and LLMs.
The Roadmap Ahead
We are continuously iterating to expand our reach and impact.
Trusted Central Hub
Becoming the go-to reference for citizens, researchers, academia, public institutions, and the broader institutional landscape.
Personalized Alerts
Rollout of tailored newsletter updates based on country, data-type preference, and compensation models.
Broadening Citizen Science
Expanding beyond personal data to environmental data collection, image classification, and crowd-sourced field research.
Multi-Language Integration
Translating the catalogue natively so science is universally accessible regardless of spoken language.
